Description
Leader of the group Stochastics: Bert Zwart.
Many natural and man-made systems and processes are driven by random phenomena. Examples can be found in areas such as communication, energy, information, logistics, and transportation systems. In order to model, describe, and improve such systems, our group develops and studies probabilistic, operational and statistical models. Our group’s analysis of these models relies on techniques from fundamental probability theory, queueing theory, stochastic scheduling, spatial stochastics and stochastic geometry. Our work with various companies in these areas, as well as with top researchers and universities across the globe, ensures our position at the forefront of every aspect of this research field.

Stokhos and LIS GmbH sign Letter of Intent in presence of state secretary Sander Dekker
On April 24 2017 CWI spin-off Stokhos and German software company LIS Leitstellen Informations System GmbH have signed a Letter of Intent in presence of State Secretary for Education, Culture and Science Sander Dekker. This happened at the Hannover Messe, the largest annual technology trade fair.
Rubicon grants for David de Laat and Alessandro Zocca
CWI researchers David de Laat and Alessandro Zocca both received an NWO Rubicon grant. De Laat will study new techniques to compute optimal packings at MIT for one year, and Zocca will study renewables and uncertainty in future power systems at Caltech for two years. NWO granted these subsidies to 22 young, highly promising research talents to gain international research experience at foreign top institutes.
CWI researcher makes higher turnover in hotel bookings possible
With a new mathematical method, hotels can receive on average 5% more turnover in the long term when taking online reviews into account. Dirk Sierag, PhD student of CWI, analysed with historical data the behaviour of consumers booking rooms. Based on the results he designed mathematical models that can support hotels in determining optimal prices of hotel rooms. The research results can also be applied on movies, concerts, sporting events and, for example, Uber taxi rides.
